' SHUTTLE-BOX-OPERAT'ING DEVICE FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 410,850, datedSeptember 10, 1889.

Application tiled July 16, 1888. Serial No. 280,095. (No model.)

To @ZZ whom it may concern.-

Be it known that I, EPHEAIM E. ORRELL, residing at Vare, in the countyof Hampshire and State of Massachusetts, have invented certain new anduseful Improvements in Shuttle-BoX-Operating Devices for Looms, of whichthe following is a full, clear, and exact description, reference beinghad to the accompanying drawings, forming part ot' this specification.

This invention relates to a device for operating the shuttle-boxes oflooms in which goods having different colors in their designs are beingwoven, and is in part an improvement on Patent No. 357 ,499, issued tome Feb? ruary 8, 1887.

The object of the invention is to obtain positive action of theshuttle-boxes, so that the box containing the shuttle carrying therequired thread will be at once and positively moved in position toallow of the throwing of the shuttle across the shed.

In the accompanying drawings, forming part of this speciiication, Figure1 is a side elevation of the frame of a loom with my improved deviceattached thereto. Figs. 2, 3, at, and 5 are side views of portions ofthe device to clearly show the successive positions of the parts inoperation. Fig. 6 is a side view of the box-operating device. Fig. 7 isa sectional view taken on the line 7 7 of Fig. 6. Fig. S is a side viewof part of the rack-operating device, the front cam being shown insection, the section being taken on the line 8 8 of Fig. 9. Fig. 9 is asectional View of part of the rack-operating device, the section beingtaken on the line 9 9 of Fig. 8. Fig. 10 is a View of the cam 23,showing the grooves in the same.

In the accompanying drawings, illustrating my invention, like numbers ofreference designate corresponding parts throughout.

Referring to the drawings, 10 represents the side frame of a loom 5 11,a frame-piece used when the device is attached to the old form of loom.In making the side frame 10 of a loom to be provided with my attachmentthe frame-piece 11 may be cast integral with the side frame of the loom,and therefore form part thereof.

The frame-piece 11 is provided with the bearing-pin 12, having the head13 and the screw-threaded portion 14, which pin is securely held inposition on the frame-piece 11 by means of the nut 15. The frame-piece11 is also provided with the two pins 16 and 17.

On the main driving-shaft 1S of the loom is secured the gear 19, whichintermeshes with and drives the gear 20, provided with the hub 21,having a nut screw-threaded on the end thereof, said gear 2O beingmounted on the bearing-pin 12.

On the hub 21 of the gear 2O are mounted the two cams 22 and 23. Thesecams 22 and 23 are secured to the gear 20 or hub 21 by a spline orotherwise, so as to revolve with the gear in the direction indicated bythe arrow A in Figs. 1, and 8. In the face of the respective cams 22 and23 are cut the grooves or ways 24 and 25. The arms or levers 26 and 27are respectively mounted on the pins 16 and 17, and are provided withthe movable bolts 28 and 29, located in and capable of being moved inthe bosses 30 and 31, formed on the inner faces of the arms 26 and 27,respectively. To the said arms 26 and 27 are pivoted the bell-cranks 32and 33. One end of each of the said bell-cranks is pivoted to themovable bolts 2S and 29, while to the other end of each of thebellcranks are connected the rods 34 and 35, which rods are operated bythe balls on the pattern-chain mechanism, so as to be lifted, therebylift-in g the lower end of the bell-crank and moving the upper end orthat connected with the bolt in toward the frame of the loom. Each ofthe bell-cranks is provided with a spring 36 37, consisting of a lengthof spring-wire one end of which isV bent so as to enter a hole in thedisk shown on the inner square end of the projectingA 9o fulcrum pin orshaft on which the bell-'crank is journaled. The wire is wound once ortwice around the fulcrum-pin and then prof IOO drawings, which shows asection of the cam 22 taken on the line S S of Fig. 9, that the groovesor ways 24 eut in said cani 22 are closed at one of their ends, and thatthe open ends lead into the groove 38, which is in the form of acomplete circle. In the cam 23 the position of the grooves is reversed,the groove or way 39 forming a complete circle, which is in the sameposition relative to the center of the cam as the circular portions ofthe ways 24 in the cani 22, and the grooves or ways 25 are closed ways,their circular portion coinciding with the circular groove 3S on the cam22 and their open ends leading into the circular groove or way 39. Thecam 2f has the ways 25 leading out from the central closed ways to thecircular groove or way 3f), as indicated in Fig. 8 by the arrows B.

It will therefore be readily seen that the operation of this part of thedevice is as follows: Upon the lower end of thc bell-crank 32 beinglifted by the rod 34 the upper end of the bell-crank, or that connectedto and moving the bolt 28, movably secured in the boss on the arm 26,will be moved in toward the frame of the loom, carrying with it the bolt28, the end of which will enter the way 25 in cam 23, and as the camsare revolved in the direction indicated by arrow A the bolt will becaused to travel from the inner circle to thc outer one, or thatdesignated 39, thereby moving the .tree end of the pivoted arm 2G awayfrom the central line. To return the arm to its normal position, theball on the pattern-chain, which has lifted the rod 34 in the common andwell-known manner, having passed, the spring 36, which was undertension, will at once depress the lower end of the bell-crank 32,carrying with it the rod 34, and will also move the upper end of saidbell-crank, carrying the bolt 2S toward the outer cam The bolt 28 willenter the groove 24 and pass therefrom into the circle 3S, whereupon thearm 26 will be returned to its normal position.

In the above description of the operation only one lever, or thatdesignated 2G, and its connecting parts are described as being operated.It is, however, evident that the lever 27 is operated in precisely thesame manner as the lever 2G, and therefore the description of theoperation of one will be sufficient Afor both.

Near the line of movement of the shuttleboxes I secure to the loom-framel0 the bracket 40, which has journaled therein the sleeve 4l, provided.on one end with the crank-arm. 42. To this sleeve 41 is secured the disk453, provided with the gear -1-4, and on the crank-arm 42 is journaledthe gear 45, carrying the arm 46, to which the crank-pin 47 is attached.Journaled on this crank-arm 42 is the idlepinion or intermediate gear4S, which intermeshes with the gear and the gear 49, secured at one endof the shaft 50. The shaft 50 is provided with the disk 5l, having thegear 52.

The stud-pins GG and 67, supporting the two gears 45 and 4S, passthrough the slots GS and (if), formed in the crai1karm 42, and, byreason of said slots the said gears 45 and 4S may be suitably adjusted.The crank-pin 47 is also supported in a slot 70, formed in thc arm 4G,whereby said pin may also be given adjustment.

Extending from the arm 53, which forms part of the bracket-picce'40, isthe bearingpin 54, (shown in dotted lines in Fig. 7,) on which areloosely pivoted two arms one foreach of the disks 43 and 5l.. The saidarms are provided at their free ends with the anti-friction rollers 5G,the object of thc rollers being to enter the depressions 57 in thediskssl and 5l and thereby lock said disks against jar or movementincidental to the running of the loom by reason of the force exerted onthe arms 55 by the springs 5S.

The gears 44 and 52 are provided with the operating racks 5) and GO,respectively. These racks are held in position by means of the lugs Gl,cast on the under side of thc bracket 40. The link is connected at oneend to the crank-pin 47 and at the other end to the rod G23, secured tothe bottom of the shuttle-boxes C, l), E, and F.

By using the intermediate pinion 4S, I am enabled to positively nievethe shuttle-box into the desired position without any yank motion-thatis, moving the boxes to ahigher position and then dropping them to the(lesired position.

Ilaving thus described the invention and its object, I will now describethe operation of the several devices composing my said invention.

In Figs. l. and 2 the device is shown in its normal position-that is tosay, when the free ends of the arms 2G and 27 are the nearesttogetherand the shuttle-box C is in positionto receive or have the shuttlethrown therefrom. For the parts to obtain the position shown in Fig.3-that is, to lift the D box into position-the following operation isnecessary: The proper ball arriving on the pattern-chain, the rod 235will be drawn up, thereby lifting the lower end of the bell-crank 325and moving the upper' end in, and with it the bolt 20 out from thegroove iSin the cam 22 and into the groove 25 of the cam 23, whence thebolt 29 will travel out to the circular groove 39, and with it the arm27 will be moved into the position shown in Fig. $3. As the arm 27 isconnected to the rack UO by means of the rod G4, the rack (l0 will bemoved in, causing the gear 52 to revolve, and with it the shaft 5() andgear 49, and through the intermediate pinion 48 the gear 45, therebymoving the crank-pin 47 into the position shown in Fig. 3 and liftingthe l) box into position by means of the connecting-link G2 and rod 63.

To obtain the position shown in Fig. 4- that is, to lift the E box intothe desired position-thc arms 26 and 27 being then in the normalposition shown in Figs. l and 2 and the proper ball arrivingon thepattern-chain,

- from the groove 38 in the cam 22 and into the groove 25 of the cam 23,whence the bolt 28 will travel out into the circular groove 39, and

with it the arm 26 will be moved into the position shown in Fig. 4, andas the arm 26 is connected to the rack 59 by means of the rod the rack59 will be moved out, causing the gear 44 to revolve, and with it thesleeve 41 and crank-arm 42, thereby moving the crankpin 47 into theposition shown in Fig. 4 and lifting the E box into position by means ofthe connecting-link 62 and rod 63.

To obtain the fourth and last position, or that shown in Fig. 5, or thelifting of the F box into position, the arms 26 and 27 being then in thenormal position shown in Figs. I and 2 and the proper balls arriving onthe pattern-chain, the rod 34 will be drawn up, thereby lifting thelower end of the bellcrank 32, moving the upper end in and with it thebolt 28 out from the groove 38 in the cam 22 and into the groove 25 ofthe cam 23, whence' the bolt 28 will travel out into the circular groove39, and with `it the arm 26 will be moved into theposition shown in Fig.4, and as the arm 26 is connected to the rack 59 by means of the rod 65the rack 59 will be moved out, causing the gear 44 to revolve, and withit the sleeve 4I and crank-arm 42, thereby moving the crank-pin 47, andat the same time the rod 35 will be drawn up, thereby lifting the lowerend of the bell-crank 33 and moving the upper end in and with it thebolt 29 out from the groove 38 in the cam 22 and into the groove 25 ofthe cam 23, whence the bolt 29 will travel out to the circular groove39,and with it the arm 27 will be moved into the position shown in Fig.3, and as the arm 27 is connected to the rack 60 by means of the rod 64the rack 60 will be moved in, causing the gear 52 to revolve, and withit the shaft 50 and gear 49, and through the intermediate pinion 48 thegear 45, thereby moving the crank-pin 47 into its highest position, andwith it the box F by means of the connecting-link 62 and rod 63.

To simplify and make the description more clear, I have described thelast operation as ocurring in two steps, whereas in point of fact, asthetwo balls on the pattern-chain arrive at the same moment, the two arms26 and 27 and their connecting parts are all moved at the same time.

In order to overcome the effect of any in'- 'equalities which may occurin the casting of the boxes, whereby the distancemight vary from one boxto another, and to enable us to present accurately all the series offour boxes at a level with the shuttle-race, according to 'the demandsof the pattern being woven, I

adopt the following method of adjustment: If the distance from thebottom of the C box to the bottom of the D box is found to be by actualmeasurement two inches, it is only necessary to place the crank-pin 47and the stud-pin 66 for gear 45 one inch from center to center. Thisalso serves for movement from E box to F box. If there is any variation,it must be divided. The adjustment for the distance from the bottom ofthe box D to the bottom of the box E is made with reference to thecenter of the shaft 50. If by actual measurement the distance is two andone-eighth inches, then the distance from the center of the crank-pin 47to the center of the shaft 50 when the crank-pin is in the positionshown in Fig. 3 or in Fig.4 must be one and one-sixteenth inch. Toadjust the intermediate gear 48 and gear 49 so as to properly mesh withthe gear 45, it will be necessary only to loosen the nut of the stud-pin66 and move the stud-pin, and with it the gear 45, so that the distancefrom the center of the crank-pin 47 when in its upper position to thecenter of the shaft 50 will be one and one-sixteenth inch, at whichpoint thc stud-pin 66 will be secured by tightening the nut, and to movesaid gear 48 down the slot 69 until it meshes properly with gear 45, andthen secure the same.

It is obvious that any desired box may be called into action wheneverdesired by the proper arrangement of the pattern-chain.

Various modifications may be made in the construction of the devicesherein shown and described wit-hout departing from the spirit of myinvention.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1.
